Book excerpt: Excerpt from Pelagic Fur Seal Investigations, Alaska, 1963 Seals were seen in groups rather than in large herds. In 1963, groups of one, two, and three seals accounted for percent of the total sightings. Of seals collected in 1963, 111 were males and were females. Five-year-olds predominated among females. The relative distribution of males and females, with only three exceptions, was fairly uniform, Post partum females predominated in the early July collections in sectors 1 and 2, zones 3 and 4, and in the feeding areas of the outer zones from mid-july to early Sep tember. The first adult males found away from the Pribilof Islands were seen 5-20 miles north west of Akun Island on 31 July. In August they were found widely scattered at sea. More males were collected in Alaska waters than in the waters off California, Oregon, and Washington. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Fur Seal Investigations: Pribilof Islands, Alaska, 1965 Estimates of the number of pups born based on the tag-and-recovery method have long been known to be inflated, mainly as a result of tag-induced mortality and loss of tags. Additional pups are now marked each year by shearing a patch of fur, and estimates of the number born are obtained by sampling for a marked-to-unmarked ratio 1 to 3 weeks later. The estimates from shearing were similar to complete counts of pups on several small rookeries. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
